Beren and Luthien

Tolkien. Returning from France and the battle of the Somme at the end of 1916, he wrote the tale in the following year. Essential to the story, and never changed, is the fate that shadowed the love of Beren and Lúthien: for Beren was a mortal man, but Lúthien was an immortal Elf.Her father, a great Elvish lord, in deep opposition to Beren, imposed on him an impossible task that he must perform before he might wed Lúthien.
